How to show decision region on iris data set for only 2 features?

Hi,

I am currently working on iris dataset. I trained my model in matlab by using all 4 features. How can I show decision regions on 2D plot. (For example: training is done by using for all 4 features and show decision region on 2D plot like sepal length vs sepal width)

Thanks in advance.
